Serial Killer with Piers Morgan

Piers confronts convicted killer Mark Riebe, who has confessed multiple times to the abduction and murder of thirteen women in Florida.

At Missouri's Crossroads Correctional Facility, Piers comes face-to-face with Lorenzo Gilyard - the Kansas City Strangler.

The broadcaster meets Bronx businessman Alex Henriquez, who was imprisoned for three murders in 1992 but has always protested his innocence.

Piers comes face-to-face with Bernard Giles, who murdered five female hitch-hikers in late 1973.
